    If your hearing a ticking/knocking noise around 900 rpms then you might have dirty injectors. Went to the local auto parts store and picked up a stethoscope to listen to the exhaust and motor. Couldn't find the noise then I bumped the fuel rail and what do you know... There it was. :jester: So then I picked up some b12 fuel injector/carb cleaner. Ran it through the brake booster line and added some to the fuel tank. Well I done this the day before my truck went into the body shop for the hail repairs. Well it's been two weeks and got it back yesterday, whatever was in the injectors making it clog or stick is now gone. Plus it took care of a miss I had. :birgits_tiredcoffee
